Design Tree Operations with DFS and BFS
Design an object-oriented tree class that supports operations requiring Depth-First Search (DFS) and Breadth-First Search (BFS) traversals. Detail the node model, the design of traversal APIs, and outline a strategy for testing these tree operations.
Constraints & Assumptions:
- The tree resides entirely in memory.
- Nodes can have an arbitrary number of children (n-ary tree).
- Both DFS and BFS traversal methods must be implemented.
- The specific operations to be implemented are open to interviewer definition and extension.
